Fix libraries on OS X
Signed-off-by: David Shah <[email protected]>
Use the GNUInstallDirs include provided by CMake to auto detect target install paths for the target system. This allows for building natively on the same host as well as enabling a distro to override the paths or for cross compiling to override the paths for the target distro/system. This removes the need to manually detect the 'lib64' directory, and also fixes the issues with using 'FIND_LIBRARY_USE_LIB64_PATHS' which is always true on targets other than debian (even if those targets do not use the 'lib64' path by default). Additionally this change calculates the relative path between bindir and libdir in order to populate the rpath information into the built binaries for supporting portable execution.

In order to execute the ecpmulti, ecppack and ecpunpack programs they must be able to access the trellis database files. These files are installed alongside the tools in the data directory (normally /usr/share). To enable portable execution of these programs such that they can access the database relative to their executables path the programs must be built with the relative path embedded and also be able to access the executables path at run time. Since libtrellis already depends on Boost it makes sense to use the Boost dll module. This module provides the 'program_location' function which can be used with the 'boost::filesystem::path' to build the absolute path to the database at run time. The only downside with the use of the Boost dll module is that a unused component of the included source relies on certain dynamic linker functions which requires linking to libdl on some platforms. This however is easily handled by the CMAKE_DL_LIBS variable which expands to the correct linker arg on targets that require linking with the dynamic linker. The Boost dll module was only added in 1.61. In order to support older versions of Boost such as that of Ubuntu 16.04 (1.58), a local implementation of 'program_location' is added which is based on the 'proc_self_dirname' implementation from yosys. This version is chosen due to its use in a number of tools similar to libtrellis (e.g. icestorm) but also due to its ISC license which matches libtrellis. This implementation is conditionally used if the Boost dll module is unavailable. The cmake configuration is also changed to generate a relative path from datadir to bindir, this path is then provided during the build as TRELLIS_RPATH_DATADIR. Note: ecppll does not currently use the trellis database Signed-off-by: Nathan Rossi <[email protected]>
