Csaba was clear but it seems you are misunderstanding,
the call to cmake is
cmake [options] <path-to-source>
No, not <path-to-source> but <path-to-CMakeLists.txt>
For quickhull, CMakeLists.txt is in the root of the project, the
sources are under the src directory.
Csaba,
you are 100 %right.
I just copied the cmake help
$ cmake --help |head -n 4
Usage
cmake [options] <path-to-source>
cmake [options] <path-to-existing-build>
where of course they consider CMakeLists.txt as part of the source
and placed in the tree root.
Regardless of where the build is performed, the path in the cmake
invocation must point to the root of the project. Copying
CMakeLists.txt into ./src and pointing cmake to ./src is unlikely to
work.
All of this is moot because the author of quickhull littered
CMakeLists.txt with clang-specific compiler switches. He made no
attempt to cater for the world's most widely used C++ compiler (GCC).
I agree on that. He made the life hard for anyone to build his software.
