Build multi project with cmake

[themean]

I want to create my game engine with cmake (thanks to ogre community for their help)
My project have some executables and some libraries(dll/so and lib/a).I want to put all libraries(dynamic and static) in single directory and link executables to them from this directory
Also I want cmake to put dynamic libraries in specific directory(game directory) after their build

CMAKE_LIBRARY_OUTPUT_DIRECTORY - For windows this is only for static libs

CMAKE_RUNTIME_OUTPUT_DIRECTORY - For windows this move all useless file (*.dll.embed.manifest, *.dll.embed.manifest.res ,*.dll.intermediate.manifest , *.dll.resource.txt , *.ilk , *.pdb) but not .lib(file with exportet symbols) that need for linking.
How people do that in their projects

For each executable/library I want in my output folder, I use the following to get it to my bin folder:

SET(EXECUTABLE_OUTPUT_PATH ${PROJECT_BINARY_DIR}/bin)

I have a configuration file for my executable files, so I also copy a fresh one of those to the bin folder as well with the following command:

add_custom_command(TARGET my_exe_name
POST_BUILD
COMMAND ${CMAKE_COMMAND} -E copy ${CMAKE_CURRENT_SOURCE_DIR}/my_exe_name.conf ${PROJECT_BINARY_DIR}/bin/$(ConfigurationName)
)

Hope that gives you some ideas.

10x but I'm new to cmake and don't know how to use add_custom_command.
Search in documentation but can't get it at 100%

I think that I get it

It is actually a better solution to use the INSTALL command from cmake and create a install target after compilation. If you want to link e.g. one of your libraries to an executable project of yours, you would use something like the following:

Code: Select all

INSTALL(TARGETS <your-lib-target>
		EXPORT <your-lib-target> 
		RUNTIME DESTINATION "bin" 
		LIBRARY DESTINATION "lib" 
		ARCHIVE DESTINATION "lib")
INSTALL(EXPORT <your-lib-target> DESTINATION "lib")

This will create a "<your-lib-target>.cmake" file in your install target's location in the "lib" directory, which can then be used in the CMakeLists.txt file of your executable project which is intended to use the library.
The directory where your install target is copied to, can be specified with the cmake install prefix.

Hope that helps
