When setting up a CLR project through CMake, it becomes important to
be able to *remove* compiler options at the project level. For
example, the following need to be removed (MSVC12):
/RTC1
/EHsc
There is no "remove_compile_options()" (which would be convenient).
Any reason why this doesn't exist?
Right now I'm trying to remove these via CMAKE_CXX_FLAGS locally but
this doesn't work unless I forcefully change the cache. But this is a
permanent operation that affects *all* projects, which I do not want.
This is crazy, I'm hoping there is a better way. I'm using CMake 3.1
RC1. Can anyone help me figure out how to remove compiler options on a
per-project basis?
Here is what I'm doing:
function( add_clr_library target_name references )
set( source_files ${ARGN} )
set( default_references
System
System.Core
System.Data
System.Drawing
#System.Xml
#WindowsBase
)
if( CMAKE_CXX_FLAGS_DEBUG MATCHES "/RTC1" )
string( REGEX REPLACE "/RTC(su|[1su])" ""
CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG}" )
endif()
if( CMAKE_CXX_FLAGS MATCHES "/EHsc" )
string( REPLACE "/EHsc" "" CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}" )
endif()
add_library( ${target_name} SHARED ${source_files} )
list( APPEND references ${default_references} )
set_target_properties( ${target_name} PROPERTIES
VS_DOTNET_REFERENCES "${references}"
VS_DOTNET_TARGET_FRAMEWORK_VERSION "v4.5"
COMPILE_FLAGS "/clr /EHa"
DEBUG_POSTFIX "d"
)
endfunction()
