CMake configuration

How this proceeds depends on whether you're building from a release
package or not.  A release package (marked by a file named VERSION at
the top level) has preprocessed man pages and so can be built without
the extra tools needed for processing the pod-style man pages; in
addition, the release package has a configure script (created by
autogen.sh) for autoconf-style builds.

CMake options and variables: see CMakeLists.txt for information

BUILD_SHARED_LIBS ON
BUILD_BOTH_LIBS OFF
BUILD_DOCUMENTATION OFF
USE_BOOST_FOR_EXAMPLES OFF
CONVERT_WARNINGS_TO_ERRORS OFF (ON in non-RELEASE mode)
BUILD_MANPAGES OFF (ON in non-release mode)
GEOGRAPHICLIB_DATA /usr/local/share/GeographicLib or C:/ProgramData/GeographicLib
GEOGRAPHICLIB_PRECISION 2
  1 = float
  2 = double
  3 = extended
  4 = quadruple (boost float128)
  5 = variable (mpreal)

Where things get installed.  Use an empty string to disable that installation

CMAKE_INSTALL_PREFIX
INCDIR "include" "Where to install header files"
BINDIR "bin" "Where to install tools"
SBINDIR "sbin" "Where to install admin tools" ("" for Windows)
LIBDIR "lib" "Where to install libraries"
  this is set to ${CMAKE_INSTALL_LIBDIR} if that's defined
DLLDIR "bin" "Where to install dlls"
MANDIR "share/man" "Where to install the man pages"
CMAKEDIR "lib/cmake/GeographicLib "Where to install cmake configs"
PKGDIR "lib/pkgconfig" "Where to install package config"
DOCDIR "share/doc/GeographicLib" "Where to install documentation"
EXAMPLEDIR "share/doc/GeographicLib-dev" "Where to install examples"

CMAKE_DEBUG_POSTFIX  "The suffix for debug objects" "_d"

Windows only
PACKAGE_DEBUG_LIBS "Include debug versions of library in binary package" OFF

CMake targets

release mode
  all test
  sanitize hygiene check on source files (trailing blanks, etc)
  exampleprograms compile example programs (this is separate cmake config)
  experimental compile experimental code
  package make binary package for Windows
  package_source make source package

maintainer
  doc (if BUILD_DOCUMENTATION and doxygen found)
  prep-source prep source distribute prior to making release package
  distrib-man create extra versions of man pages
  distrib-all distrib-man + run autogen for autoconf builds
  dist Package release into a tar.gz + zip files
  stage-doc copy documenation to staging area
  stage-dist copy source distribution to data-distrib
  deploy-doc deploy documentation from staging area to sourceforge
  deploy-dist deploy source distributions from data-distrib to staging
    area and then to sourceforge
  deploy-data deploy geoid data etc
  develprograms build experimental stuff

Version update checks

Add PROJECT_VERSION_SUFFIX = "-alpha" to
  tar package of source

Do not add PROJECT_VERSION_SUFFIX to
  unpack directory for tar package
  documentation

binaries for cgi scripts
run compile.sh (copy in cgi-bin)

When ready for switch over, do
cd /home/project-web/geographiclib
rm bin
ln -s bin-$VERSION bin

make -f makefile-admin distrib-cgi
update binaries for cgi applications

Release checklist:

Merge all changes to main
test-distribution.sh: set SUFFIX= and BRANCH=main
CMakeLists.txt set PROJECT_VERSION_SUFFIX suffix to ""
pom.xml keeps SNAPSHOT for now
Update NEWS
Set date in NEWS and GeographicLib.dox.in
run develop/test-distribution.sh
run windows build
copy windows installers to data-distrib/distrib-C++
fix permissions on installers
remove alpha/rc versions of installers
switch C++/doc link to latest version
In build directory:
  make clean
  make -j10 all
  make stage-{doc,dist}
  make deploy-{doc,dist}
checkin and tag release branch & push
tag main branch

trigger build on build-open

update binaries for cgi applications
  make stage-cgi deploy-cgi
  ssh -t karney,geographiclib@shell.sourceforge.net create
  update VERSION in compile.sh and compile

Local install
sudo make -C $TEMP/relc/GeographicLib-$VERSION/BUILD-system install

set default downloads for distrib-C++ on sourceforge
