Hi. What scl enable devtoolset-2 does, is basically change the environment for the command. I use one of two techniques to make it working. When doing manual builds, I simply: scl enable devtoolset-2 bash And do everything from the new shell. On our CI, I put the following in build script (before calling cmake): . /opt/rh/devtoolset-2/enable As there is no magic but only environment variables involved, you can probably set them all using -DCMAKE_... options. Just look at the script and set, what you need. Remember, that devtoolset-2 is really just GNU Toolset in 4.8 version installed in non-standard location.

In particular variables like the following could be used: -D CMAKE_C_COMPILER="ccache" -D CMAKE_C_COMPILER_ARG1="gcc" The picture becomes more complicated when the tools around the real compiler requires "special" syntax. As an example the RedHat's scl is such a one as it's requires quotation of the complete compiler line: scl enable devtoolset-2 'g++ -o output_file source_file...' Details: https://access.redhat.com/site/documentation/en-US/Red_Hat_Developer_Toolset/2/html/User_Guide/sect-GCC-CPP.html I was playing with build rules, however didn't success on try_compile which seems to ignore them. set ( CMAKE_C_COMPILE_OBJECT "<CMAKE_C_COMPILER> enable devtoolset-2 ' gcc <DEFINES> <FLAGS> -frandom-seed=<SOURCE>/ -o <OBJECT> -c <SOURCE>' ") The only working one that I found is to use small bash script which will act as yet another wrapper. Anyway this solution do not looks "elegant" and I would like to avoid. Can anyone suggest a good method how to cope with this issue ? -- Pozdrawiam/Best regards/Mit freundlichen Grüßen, Tomasz Majchrowski, Information Technology and Services Consultant and Contractor -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
