Static build fails with DTCMP/LWGRP error when examples enabled

[CamStan]

Building SCR statically, with DTCMP/LWGRP also built statically, fails

First encountered this when testing the Spack builds. Was able to replicate it with bootstrap.sh.

How to Reproduce

Using bootstrap.sh from PR #452, build the deps.
Then configure scr with -DENABLE_IBM_BBAPI=OFF and -DBUILD_SHARED_LIBS=OFF and build:

$ ./boostrap.sh --debug --dev --static
$ mkdir -p build && cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/path/to/scr/install -DSCR_RESOURCE_MANAGER=LSF -DENABLE_IBM_BBAPI=OFF -DBUILD_SHARED_LIBS=OFF ..
$ make VERBOSE=1

Workaround

Disabling the examples allows the build to succeed:

$ cmake -DCMAKE_INSTALL_PREFIX=/path/to/scr/install -DSCR_RESOURCE_MANAGER=LSF -DBUILD_SHARED_LIBS=OFF -DENABLE_IBM_BBAPI=OFF -DENABLE_EXAMPLES=OFF ..
$ make
$ make install
