Subject: [PATCH] cmake: initialize variables where missing

As detected using `cmake --warn-uninitialized`.

It also lists documented CMake global variables, which is unexpected:
`CMAKE_MODULE_PATH`, `CMAKE_IMPORT_LIBRARY_SUFFIX`.
I'd expect CMake to initialize its namespace.

https://cmake.org/cmake/help/latest/manual/cmake.1.html#cmdoption-cmake-warn-uninitialized

Closes #1539
