Description:
The cmake code for checking "system" zlib resets CMAKE_REQUIRED_LIBRARIES
This may break any subsequent feature tests.

How to repeat:
Build on Solaris -DWITH_ZLIB=system, InnoDB feature tests will fail.

Suggested fix:
Don't reset CMAKE_REQUIRED_LIBRARIES, as setup by configure.cmake

Posted by developer:
 
Fixed in 5.7.22, 8.0.5.

-DWITH_ZLIB=system could cause other CMake feature tests to fail.
