Summary: Add CLR support for MSVC C++ Projects
Description:
Hi,
I would like to use CMake to create MSVC .vcproj files that have the "Common
Language Runtime support" enabled.
After doing some research and hacking on my own, I would like to present the
results to you; maybe you´d like to polish and integrate these changes into a
future release of CMake.
Basically, I did these things:
- Add a CMake option called "ENABLE_CLR"
- Add the "ManagedExtensions" item below the "CharacterSet" item in the .vcproj;
Set the value of "ManagedExtensions" to "1" if CLR support is desired, "0"
else
- Remove the /EHsc compiler flag (does not work with CLR)
- Remove the /RTC1 compiler flag (does not work with CLR)
The code snippet sent as additional information shows my modifications in
cmLocalVisualStudio7Generator.cxx.
If you have any questions, feel free to ask.
