[CMake] Visual Studio /AI and /clr compiler option

[Pierluigi Taddei]

I have a project that makes use of managed code and is compiled using 
the /clr option.

1 ) In order to set up cmake correctly I had to issue the following command:

SET_TARGET_PROPERTIES(${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "/clr")  
#mark as managed code

This was not sufficient because cmake added other options by default 
(/EHsc and /RTC1) which are not compatible with /clr.
I had to disable them by manually replacing the cmake flags strings:

if(CMAKE_CXX_FLAGS_DEBUG MATCHES "/RTC1")
   string(REPLACE "/RTC1" " " CMAKE_CXX_FLAGS_DEBUG 
"${CMAKE_CXX_FLAGS_DEBUG}")
   message(STATUS ${PROJECT_NAME}  " CMAKE_CXX_FLAGS_DEBUG removing /RTC1")
endif()

if(CMAKE_CXX_FLAGS MATCHES "/EHsc")
   string(REPLACE "/EHsc" "" CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}")
   message(STATUS ${PROJECT_NAME}  " CMAKE_CXX_FLAGS removing /EHsc")
endif()

Is this the only way to perform that or there is a more elegant way?


2) In the same managed project I am importing 3rd party dlls which are 
referenced in the code as

#using [3dpparty.dll]

In order to set up the folder containing the dlls I use the visual 
studio compiler option /AI (which corresponds to the "Resolve #using 
Reference" field in the project properties).
Since I did not find a way to fix it explicitly using a cmake command I 
modified the cmake compiler flags as follows:

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /AI\"${3DPARTY_FOLDER}\" ")

Again, is this the only way to perform that or there is a more elegant way?

Thanks,
