gettext required

[dschwoerer]

If configuring without gettext, BOUT++ notices that, and skips it: -- Could NOT find Gettext (missing: GETTEXT_MSGMERGE_EXECUTABLE GETTEXT_MSGFMT_EXECUTABLE)

However, later on requiring BOUT++ fails with:

-- Found SUNDIALS: ~/local/lib/libsundials_[nvecparallel.so](http://nvecparallel.so/);~/local/lib/libsundials_[arkode.so](http://arkode.so/);~/local/lib/libsundials_[cvode.so](http://cvode.so/);~/local/lib/libsundials_[ida.so](http://ida.so/) (found suitable version "5.4.0", minimum required is "5.4.0")

Do we have a check that the bout++Config.cmake is working? Like compiling some minimal BOUT++ program, and check that it is running?

[ZedThree]

We've got a bout-config test with CMake, but not a bout++Config.cmake test.

Should be as "simple" as:

cd examples/conduction
cmake . -B build -DCMAKE_PREFIX_PATH=../../build
cmake --build build
./build/conduction
