With CMake 3.11, configure fails with this error:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
MYSQL_EMBEDDED_LIBRARIES
linked by target "cmTC_ec547" in directory /wrkdirs/usr/ports/databases/soci/work/soci-3.2.2/CMakeFiles/CMakeTmp
CMake Error at /usr/local/share/cmake/Modules/CheckIncludeFile.cmake:60 (try_compile):
Failed to configure test project build system.
Call Stack (most recent call first):
/usr/local/share/cmake/Modules/FindThreads.cmake:121 (CHECK_INCLUDE_FILE)
core/CMakeLists.txt:17 (include)
The underlying issue is that the test for MySQL embedded leaks the
library into CMAKE_REQUIRED_LIBRARIES, which are then picked up in
other feature tests. If the library wasn't found (which is normal,
it's not a dependency in the port) then those later tests fail.
CMake 3.11 is somehow stricter about this than CMake 3.10.
No PORTREVISION bump because it's a pre-emptive build fix and nothing
changes on the port.

Prevent CMAKE_REQUIRED_LIBRARIES from leaking out of this module.

If the embedded libs are not found, we don't want to have the
|
|
not-found libraries required by other modules.
