Compiler and linker options
---------------------------
CMake lets you specify a few variables to control the behavior of the
compiler and linker. These flags are rarely used but can be useful for
64-bit to 32-bit cross-compilation.
There are several options that control the behavior of the compiler and
linker. These flags may be useful for cross-compilation or specialized
setups.
- `CMAKE_C_FLAGS`: Set your own compiler flags
- `C_STANDARD`: the C standard to compile against; defaults to `C90`
- `C_EXTENSIONS`: whether compiler extensions are supported; defaults to `OFF`
- `CMAKE_FIND_ROOT_PATH`: Override the search path for libraries
- `ZLIB_LIBRARY`, `OPENSSL_SSL_LIBRARY` AND `OPENSSL_CRYPTO_LIBRARY`:
Tell CMake where to find those specific libraries
