tlbuild: kpathsea library

 
 6.4.4 The 'kpathsea' library in 'texk/kpathsea'
 -----------------------------------------------
 
 This is one of the TeX-specific libraries that are maintained as part of
 TeX Live (⇒(kpathsea)); the other is 'ptexenc'.  These TeX
 libraries are Libtool libraries (static and/or shared) and are installed
 by 'make install' together with the programs.  They are, however, not
 part of the TL DVD as distributed by TeX user groups, and have never
 been officially released for standalone use.
 
    It is possible, and probably useful for distro builds (⇒Distro
 builds), to specify the configure option '--with-system-kpathsea' in
 order to use a system version of the library.  Programs outside the TL
 tree should use 'pkg-config' for the required flags.
 
    In addition to 'kpathsea/ac/withenable.ac' and
 'kpathsea/ac/kpathsea.ac' here there is a third fragment
 'kpathsea.ac/mktex.ac', included by both 'withenable.ac' and
 'configure.ac', which supplies configure options such as
 '--enable-mktextfm-default'.  These determine the compile time default
 of whether or not to run 'mktextfm' (and similar) to generate a missing
 '.tfm' (or whatever) file.  In any case, however, the command line
 options '-mktex=tfm' or '-no-mktex=tfm' for the TeX-like engines
 override this default.
