cmake: Respect --prefix for headers during cmake --install

Browse Source 
Removing CMAKE_INSTALL_PREFIX allows for `cmake --install <build-dir>
--prefix=<installation-prefix>` to install headers at
`<installation-prefix>/include` at install time.

When CMAKE_INSTALL_PREFIX is present in `INSTALL()`, it is hard-coded
during configuration (e.g., `cmake -S .`), which disallows it from being
set at install time.
