How to avoid race when two cmake --build
are run in parallel, for the same cmake build directory?
For example, if I want to have cmake --build . --target Alice
and cmake --build . --target Bob
in parallel,
and both of the targets depends on Foo
.
How to ensure Foo
is built only once without race?
Why I need to call two cmake --build
in parallel?
I need to call CMake from another build system, in order to specify dependency.
I am using Linux with ninja-build generator
