Escape colon character in LAPACK_LIBS string

[kilicomu]

The colon character is getting passed through to a make target unescaped, which causes the test for LAPACK libraries to fail.

[kilicomu]

Initially, I'm not sure how this change will affect the CI builds, so I'm opening in draft to see what happens when the LAPACK libs are visible to SUNDIALS.

Doesn't look like escaping the colon has led to functional LAPACK. In my head this means that the build couldn't find the LAPACK libraries at the specified location, so I need to poke around in the build.

[kilicomu]

LAPACK is now functional in the CVODE build, but we're in the same position that I am on my system - undefined symbols in the CVODE libraries which propagate through to the AtChem2 build:

/usr/bin/ld: cvode/lib/libsundials_cvode.so: undefined reference to `dgbtrs_'
/usr/bin/ld: cvode/lib/libsundials_cvode.so: undefined reference to `dcopy_'
/usr/bin/ld: cvode/lib/libsundials_cvode.so: undefined reference to `dscal_'
/usr/bin/ld: cvode/lib/libsundials_cvode.so: undefined reference to `dgetrf_'
/usr/bin/ld: cvode/lib/libsundials_cvode.so: undefined reference to `dgbtrf_'
/usr/bin/ld: cvode/lib/libsundials_cvode.so: undefined reference to `dgetrs_'

(https://github.com/AtChem/AtChem2/pull/459/checks?check_run_id=3349186758#step:12:40)

I guess this means that CVODE isn't correctly linking to OpenBLAS, as these symbols are found in the OpenBLAS library (at least on my system - worth checking in the CI build...).

[kilicomu]

The symbols are definitely present in OpenBLAS lib: https://github.com/AtChem/AtChem2/pull/459/checks?check_run_id=3349428841#step:7:1

So, need to look at the SUNDIALS build to see what's going wrong.
