I want to build a test in parallel. > How are you calling ctest? ctest -V -R '^DDOTUT_x11$' I'm only running one test executable at a time. > cmake cmake -DCMAKE_TOOLCHAIN_FILE=../../Build/buildconfigs/any-linux-gcc-x86_64.cmake ../../Build The build system we have contains 30 odd external libraries and about 40 of our own. > make make -j8 This builds everything but the tests. We've been leaving the build of the tests to ctest upto now. However ctest now appears to be building more than just the tests. Its not rebuilding everything just some of the libraries. make on its own seems to respect the dependencies and only rebuild what is required unless I've run ctest.
