This was fixed in issue1076, now both places use "SoPlex".

The warning is a bit odd anyway because CMake is case-independent, so complaining that strings do not match in their upper/lower case is unexpected.

CMake generates the following warning because the CMake module to find SoPlex uses "soplex" in one place and "SoPlex" in another. We have to find out if we can change one of them, so the capitalization is unique.

CMake Warning (dev) at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
  The package name passed to `find_package_handle_standard_args` (soplex)
  does not match the name of the calling package (Soplex).  This can lead to
  problems in calling code that expects `find_package` result variables
  (e.g., `_FOUND`) to follow a certain pattern.
