Hi,
Just wanted to put an update for the CMakeLists.txt since I forgot to CC to
the mailing list, apologies.
Also, since I forgot to CC my previous email about this, maybe we just
remove glp_netgen_prob from netgen.c and glpk.h since it is not called and
causes linker error when building DLL on Windows since glp_netgen_prob is
listed in the .def file?
I saw the other possible change as mentioned in
https://www.mail-archive.com/[email protected]/msg01020.html; maybe that
could be done officially?
Best,
Derek

##
# Usage
# =====
#
# This section provides some brief instructions on how to compile, test, and
# install GLPK using CMake. Although currently configured only for use on
# Windows, the config can be extended to support *nix systems as well.
#
# Note:
#
# This file can be split up into smaller .cmake files if desired. It is a few
# hundred lines long unfortunately in large part since the sources are all
# listed explicitly instead of using globs and because of the install logic.
#
# Windows
# -------
#
# The following items are values to be determined by the user. They are used in
# the build commands enclosed in brackets to distinguish them.
#
# Arch: Win32, x64
# Config: Debug, Release
# Prefix: (desired install root)
#
# Building
# ~~~~~~~~
#
# Note:
#
# Building dynamically, i.e. with -DBUILD_SHARED_LIBS=ON, will result in a
# linker error about an unresolved external symbol (glp_netgen_prob). The
# definition of this function is nowhere to be found in the GLPK source. To fix
# this, glp_netgen_prob needs to be removed from the .def file. It is also
# better that glp_netgen_prob is simply commented out from glpk.h too.
#
# Build static linking against C runtime dynamically + also build examples:
#
# cmake -S . -B build_windows_[Arch] -A [Arch]
# cmake --build build_windows_[Arch] --config [Config] -j
#
# Build dynamic linking against C runtime statically + no examples:
#
# cmake -S . -B build_windows_[Arch] -A [Arch] -DBUILD_SHARED_LIBS=ON ^
# -DGLPK_USE_STATIC_CRT=ON -DGLPK_BUILD_EXAMPLES=OFF
# cmake --build build_windows_[Arch] --config [Config] -j
#
# Build dynamic linking against C runtime dynamically + also build examples
# while installing with multi-configuration install tree:
#
# cmake -S . -B build_windows_[Arch] -A [Arch] -DBUILD_SHARED_LIBS=ON ^
# -DGLPK_INSTALL_MULTI_CONFIG=ON
# cmake --build build_windows_[Arch] --config [Config] -j
#
# Testing
# ~~~~~~~
#
# Note:
#
# Testing a dynamic build's example programs will result in an exit code of
# C0000135 since PATH must be updated or the DLL must be in the working
# directory for correct run-time loading. The example programs assume their
# inputs are in the current directory which makes this difficult.
#
# ctest --test-dir build_windows_[Arch] -C [Config] -j
#
# Install
# ~~~~~~~
#
# cmake --install build_windows_[Arch] --prefix [Prefix] --config [Config]
#
# If GLPK_INSTALL_MULTI_CONFIG is specified, and assuming that we are building
# shared libraries, the install tree looks like this:
#
# install_root/
# bin/
# Debug/
# glpk.dll
# glpsol.exe
# Release/
# glpk.dll
# glpsol.exe
# include/
# glpk.h
# lib/
# Debug/
# glpk.lib
# glpk.pdb
# Release/
# glpk.lib
#
# Otherwise, we have a flat install with "d" suffices, e.g.
#
# install_root/
# bin/
# glpk.dll
# glpkd.dll
# glpsol.exe
# glpsold.exe
# include/
# glpk.h
# lib/
# glpk.lib
# glpkd.lib
# glpkd.pdb
