Copy external dlls doesn't work in my setup...

[BrescaMatej]

I'm trying to integrate PhysX into my project using cmake, the PhysX library is added to my project as git submodule, currently i got to the point where I can use the library in my project but it seems that some cmake variables are not set correctly and i dont have a clean setup to continue working.

The issue im finding is that the "engine\external\physx\physx\source\compiler\cmake\windows\CMakeLists.txt" tries to copy dlls from folders that don't exist on my drive , the commented out lines are the ones that i've disabled in order to make CMake finish configurating and generating files.

# copy the external dlls
IF(PX_COPY_EXTERNAL_DLL OR PUBLIC_RELEASE)
	IF(NOT PHYSX_SLN_PHYSXDEVICE_PATH)
		SET(PHYSX_SLN_PHYSXDEVICE_PATH "$ENV{PM_PhysXDevice_PATH}/bin/x86/" CACHE INTERNAL "PhysX device copy path")
	ENDIF()

	IF(NOT PHYSX_SLN_FREEGLUT_PATH)
		SET(PHYSX_SLN_FREEGLUT_PATH "$ENV{PM_freeglut_PATH}/bin/" CACHE INTERNAL "PhysX freeglut copy path")
	ENDIF()

	IF(CMAKE_CL_64)
		#FILE(COPY ${PHYSX_SLN_PHYSXDEVICE_PATH}/PhysXDevice64.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_DEBUG})
		#FILE(COPY ${PHYSX_SLN_PHYSXDEVICE_PATH}/PhysXDevice64.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_PROFILE})
		#FILE(COPY ${PHYSX_SLN_PHYSXDEVICE_PATH}/PhysXDevice64.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_RELEASE})
		#FILE(COPY ${PHYSX_SLN_PHYSXDEVICE_PATH}/PhysXDevice64.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_CHECKED})

		#FILE(COPY ${PHYSX_SLN_FREEGLUT_PATH}/win64/freeglutd.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_DEBUG})
		#FILE(COPY ${PHYSX_SLN_FREEGLUT_PATH}/win64/freeglut.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_PROFILE})
		#FILE(COPY ${PHYSX_SLN_FREEGLUT_PATH}/win64/freeglut.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_RELEASE})
		#FILE(COPY ${PHYSX_SLN_FREEGLUT_PATH}/win64/freeglut.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_CHECKED})
	ELSE()
		FILE(COPY ${PHYSX_SLN_PHYSXDEVICE_PATH}/PhysXDevice.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_DEBUG})
		FILE(COPY ${PHYSX_SLN_PHYSXDEVICE_PATH}/PhysXDevice.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_PROFILE})
		FILE(COPY ${PHYSX_SLN_PHYSXDEVICE_PATH}/PhysXDevice.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_RELEASE})
		FILE(COPY ${PHYSX_SLN_PHYSXDEVICE_PATH}/PhysXDevice.dll DESTINATION ${PX_EXE_OUTPUT_DIRECTORY_CHECKED})
	ENDIF()
ENDIF()

the "$ENV{PM_PhysXDevice_PATH}" and "$ENV{PM_freeglut_PATH}" are empty when i print them out , and also the "/bin/x86/" is folder that is not generated , instead i get "win.x86_64.vc143.mt" folder that has the checked , debug, profile and release subfolders containg the dlls...

I didn't try to change those paths manually because I've already integrated PhysX library in my older project by manually copy/pasting source files and dlls to output directory, i don't want to do that again

So im wondering if there are some steps I've missed in my setup or maybe there's something i can do to initialize those values correctly to be in sync with the workflow im currently using...

Below is the part of my project's cmakelists.txt that im using to setup PhysX , I've found the example that uses most of these settings
