Project name in root CMakeLists.txt

[remia]

Trying to install yaml-cpp 0.7.0 on Windows, I see that the default install directory is YAML_CPP instead of the expected yaml-cpp directory under the CMAKE_SYSTEM_PREFIX_PATH . It looks like it corresponds to the project name under CMake. Is that expected behaviour? It makes a basic find_package(yaml-cpp 0.7.0 REQUIRED) fails, though can probably be fixed using the NAMES hint but is still weird default.

cmake \
  -DCMAKE_BUILD_TYPE=Release \
  -DCMAKE_POSITION_INDEPENDENT_CODE=ON \
  -DBUILD_SHARED_LIBS=ON \
  -DYAML_CPP_BUILD_TESTS=OFF \
  -DYAML_CPP_BUILD_TOOLS=OFF\ 
  -DYAML_CPP_BUILD_CONTRIB=OFF \
  ../.

cmake --build . --target install --config Release --parallel
