CMake-3.30.2

Installation of highway

Install highway by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=/usr \
      -D CMAKE_BUILD_TYPE=Release  \
      -D BUILD_TESTING=OFF         \
      -D BUILD_SHARED_LIBS=ON      \
      -G Ninja ..                  &&
ninja

This package does come with a test suite, but it requires gtest, which is not in BLFS.

Now, as the root user: 

ninja install

Command Explanations

-D BUILD_TESTING=OFF: This parameter disables the test suite from being built because gtest is not part of BLFS. Without this parameter, CMake will download this package during the configuration process. If you wish to run the tests, install gtest and then remove this parameter.

-D BUILD_SHARED_LIBS=ON: This parameter enables building shared versions of the libraries instead of static versions.
