I'm a newcomer to cmake so if I'm missing something obvious please point it
out. Having said that, despite reading the online documentation and doing a
fair amount of googling I haven't found a solution.
Specific Questions
====================
1) Is there a target/generator or some other configuration that will allow
'automatic' building of CLR targets with the appropriate compiler flags?
2) Is there a recipe for removing flags from COMPILE_FLAGS so I can build my
own options?
3) Is CMAKE_CXX_FLAGS the correct variable to tweak for Visual Studio 2010
compilation flags ? If so, can you suggest a reason why the recipe I'm using
below isn't producing the desired results ?
Background to Problem
======================
We have some C code which can be either compiled into an embedded target or
built into an emulation of that target running under .Net on windows. Cmake
seems like it would be a good solution to allow us to maintain a single set of
project configurations and we've already successfully converted the embedded
target configuration to cmake.
For windows 7, when running under .net, there are a number of specific compiler
flags that need to be used to correctly build the project...
/CLR - used to indicate that this is a CLR target
/TP - used to indicate that '.c' files should be treated as c++
/FUpathToDll - used to indicate that namespaces and unresolved references may
be found within the specified dll
I've generated a minimal test project using
>cmake -G " Visual Studio 10 Win64" (Note cmake is 2.8.4)
and have created a CMakeList.text that includes
cmake_minimum_required (VERSION 2.6)
project (test)
add_subdirectory("src")
set_source_files_properties(src/main.c PROPERTIES COMPILE_FLAGS "/CLR /TP
/FUotherstuff.dll")
add_executable(test src/main.c)
There is a also an empty cmakelists.txt in the src subdirectory to keep cmake
happy.
The problem is that when trying to build ALL_BUILDS, cmake's idea of which
compiler flags to use is not compatible with the additional flags I'd like to
use. Here's some sample output.
Note the error "cl : Command line error D8016: '/RTC1' and '/clr' command-line
options are incompatible"

This link: http://www.mail-archive.com/[email protected]/msg34975.html and this
link http://www.cmake.org/pipermail/cmake/2010-June/037346.html suggest that
modifying CMAKE_CXX_FLAGS will allow the removal of the conflicting flags.
Unfortunately I can't get this to work at all. The following cmakelist.txt...
----
cmake_minimum_required (VERSION 2.6)
project (test)
STRING(REPLACE "/EHsc" "/EHa" CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS})
STRING(REPLACE "/RTC1" "" CMAKE_CXX_FLAGS_DEBUG ${CMAKE_CXX_FLAGS_DEBUG})
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /clr")
add_subdirectory("src")
add_executable(test src/main.c)
---
Still results in this clcompile step (note incorrect flags)
ClCompile:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\x86_amd64\CL.exe
/c /Zi /nologo /W3 /WX- /Od /Ob0 /D WIN32 /D _WINDOWS /D _DEBUG /D
"CMAKE_INTDIR=\"Debug\"" /D _MBCS /Gm- /RTC1 /MDd /GS /fp:precise /Zc:wchar_t
/Zc:forScope /Fo"test.dir\Debug\\" /Fd"C:/work/cmaketest/Debug/test.pdb" /Gd
/TC /errorReport:queue src\main.c /Zm1000 main.c
I've also tried likely permutations of the above, reordering of the step etc
without any luck.
Thanks in advance for any help you can offer,
Neil
