fail to build on Debian sid

[redguy]

When trying to build in Debian sid cmake fails with:

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_LIBRARIES_atomic
    linked by target "mydumper" in directory /<<PKGBUILDDIR>>
    linked by target "myloader" in directory /<<PKGBUILDDIR>>

-- Configuring incomplete, errors occurred!

Building works when using https://cmake.org/Wiki/CMakeUserFindMySQL instead of included FindMySQL.cmake

See Debian bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=841607 for more detail

Well, after further investigation it seems that the cmake.org module doesn't do the same job as the bundled one does - it only links to libmysqlclient.so and doesn't set MYSQL_CFLAGS. Since the build succeeded without them anyway maybe they are not needed at all ?
