I am considering switching a cross platform project from separate build management systems in Visual C, XCode and makefiles to CMake. One essential feature I need is to add automatically all fil. Apple garageband system requirements. # CMAKE generated file: DO NOT EDIT! # Generated by 'Unix Makefiles' Generator, CMake Version 3.17 # Default target executed when no arguments are given to make. Defaulttarget: all.PHONY: defaulttarget # # Special targets provided by cmake. # Disable implicit rules so canonical targets will work. The feature is implemented in CMake via a new target property, WINDOWSEXPORTALLSYMBOLS. When enabled, this property causes CMake to automatically create a.def file with all symbols found in the input.obj files for a SHARED library on Windows. The.def file will be passed to the linker causing all symbols to be exported from the DLL. Download michael schumacher world tour kart software full. The book covers all of CMake in three parts. Part I: Fundamentals. The first part teaches you the CMake language: application and library targets, variables and their scopes, flow control, functions, properties and splitting up projects into subdirectories. This is normally enough. See the cmake-generator-expressions(7) manual for available expressions. Only the 'Ninja Multi-Config' generator supports a property value that varies by configuration. Easypower with crackers. For all other generators the value of this property must be the same for all configurations.

Hi,
I need to copy external shared libraries (DLLs on Windows) next to the generated executable. Is calling 'cmake -E copy_if_different' through a custom command added to the executable target still the best way to achieve this? CMake tracks include directories, compile definitions or options, link flags, etc. through its dependency system, but it doesn't provide an easy way to list / copy all shared libraries a target depends on?
I am trying to follow the 'new' CMake paradigms, using add_subdirectory(), set_target*() with PUBLIC/PRIVATE/INTERFACE scope, etc. to create a modular, re-usable setup, but that actively prevents me from using a custom command on the executable target. To wit:
App depends on Lib. Lib depends on several third-party, pre-built DLLs and encapsulates the logic of when to depend on them. The third-party, pre-built shared libraries (DLLs) are located through custom Find*.cmake modules and used as IMPORTED targets.
/CMakelists.txt
/App
/CMakelists.txt
/Lib
/CMakelists.txt
/CMakelists.txt
*************
set(CMAKE_MODULE_PATH '<my_modules>')
project('DLLTest')
add_subdirectory('${CMAKE_CURRENT_SOURCE_DIR}/Lib')
add_subdirectory('${CMAKE_CURRENT_SOURCE_DIR}/App')
/App/CMakelists.txt
*****************
add_executable(App WIN32 main.cpp)
target_link_libraries(App PRIVATE Lib)
/Lib/CMakelists.txt
****************
add_library(Lib STATIC lib.h lib.cpp)
target_include_directories(Lib PUBLIC '${CMAKE_CURRENT_SOURCE_DIR}')
if(Lib_NEEDS_DEPENDENCY)
find_package(Dependency REQUIRED)
target_link_libraries(Lib PUBLIC Dependency::Dependency)
endif()
FindDependency.cmake
********************
[snip]
add_library(Dependency::Dependency SHARED IMPORTED)
set_target_properties(Dependency::Dependency PROPERTIES
INTERFACE_INCLUDE_DIRECTORIES 'inc'
IMPORTED_IMPLIB 'dependency.lib'
IMPORTED_LOCATION 'dependency.dll'
)
In this setup, it is impossible to propagate a shared library (DLL) from Lib to App. This is because Lib and App have different BINARY_DIRs and Lib must create its target before App calls target_link_libraries(). That means that Lib does not know where App will generate its executable. If Lib is a SHARED target, I cannot set its RUNTIME_OUTPUT_DIRECTORY to be the same as App's. If Lib depends on IMPORTED targets (as is my case), I cannot create either a file(COPY) step, or an install(FILES) step, or even an add_custom_command() step in Lib to copy the shared library, because I don't know the destination.
The only solution, it would seem, is to add a custom command to App's target, because then I know where to copy the shared libraries to. But that means that App now has to know it needs to copy a shared library from a 'hidden' dependency of Lib. App also needs to know about every SHARED or IMPORTED target Lib depends on, not to mention duplicate the logic in Lib's CMakelists.txt that decided whether Lib depends on Dependency in the first place.
I was looking into GetPrerequisites and FixupBundle, but both of those operate on an already existing executable and try to guess what shared libraries (DLLs) it might need. It feels silly to guess at something that CMake already knows (as the IMPORTED target sets the IMPORTED_IMPLIB and IMPORTED_LOCATION properties).
Setting a common CMAKE_RUNTIME_OUTPUT_DIRECTORY for both App and Lib is problematic if I have multiple executables in my root CMakelists.txt and they depend on different versions of the shared libraries or I have other name clashes.
Is there no automated way to get the list of shared libraries a target depends on?
Thanks,
Marek
