Fix for TeX Live TEXMFLOCAL

[yitzchak]

TeX Live TEXMFLOCAL has multiple paths separated by a colon. Last path in list appears to be "/usr/share/.."

The fix works on some systems, but on others cmake complains with

string sub-command REPLACE requires at least four arguments.

I have no idea why... (cmake version on these systems is 3.2.2, but it works on others with 3.2.2, so I am puzzled).

[yitzchak]

Any specific systems? In any case, I can do some more research and see if I can figure it out.

I already have it installed as a patch in the Arch PKGBUILD so it isn't high priority.

The Ubuntu 14.04 systems on Travis CI. It works when I specify the gcc build environment, but fails when I choose clang... It also fails on their OS X container with the same error.

[yitzchak]

I think that TEXMFLOCAL is undefined in the clang on Travis-CL. Quotes might fix it.

[kpeeters]

Didn't fix it, but you are right, some containers have empty TEXMFLOCAL. Will think of a workaround later, need to get master back to building state now to test some more important things.

Travis-CI does not appear to have TeX installed by default. Executing kpsewhich in .travis.yml fails.

For gcc platforms TeX gets installed by:

- if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then if [[ "`${CC} --version |grep gcc`" != "" ]]; then sudo apt-get install --yes doxygen graphviz texlive-font-utils; ./config/publish-doxygen; fi; fi

Adding:

- if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then sudo apt-get install -y texlive-latex-base; fi
- if [[ "$TRAVIS_OS_NAME" == "osx" ]]; then wget http://mirror.ctan.org/systems/mac/mactex/BasicTeX.pkg -O "/tmp/BasicTeX.pkg"; sudo installer -pkg "/tmp/BasicTeX.pkg" -target /; rm /tmp/BasicTeX.pkg; export PATH=/usr/texbin:$PATH; fi

seems to fix for all platforms.
