Hello list,
I came across this problem when I tried to write a CMakeLists.txt that
prevents building in the source tree. So I would try something like this:
string(COMPARE EQUAL "${CMAKE_SOURCE_DIR}" "${CMAKE_BINARY_DIR}"
_is_in_src)
if(_is_in_src)
file(REMOVE_RECURSE ${CMAKE_SOURCE_DIR}/CMakeFiles
${CMAKE_SOURCE_DIR}/CMakeCache.txt)
message(FATAL_ERROR "Aborting...in-source builds are forbidden")
endif(_is_in_src)
When running "cmake ." the error is given as expected. However, the
source directory is polluted with CMakeFiles and CMakeCache.txt. I
expect they can't be removed while the CMakeLists.txt is being
interpreted (perhaps they are but are just created before exit again).
Is there a better way to do this? Perhaps some function/macro that
aborts the process abnormally, cleaning up as if nothing ever happened
exists?
Hi Ben,
I have found that doing an "out-of-source" build makes it much
easier to do clean up.
For example :
$cd /tmp/<some-dev-dir>
$cmake <cmake-flags-you-want> /home/ben/project/myawesomeproject
Hope that helps.
Cheers
