This question is about any desktop application on a Unix system, or at least any built with CMake. It's not specific to PerfectTIN; I'm not asking how to handle a dot which, because of roundoff error, is not inside the triangle it's in. Would it make more sense to create a list for programming questions that are not specific to an application?

Pierre,
Forgive me if I'm a party killer, but why don't you request OSGeo SAC/Admins
to create a mailing list on https://lists.osgeo.org/ dedicated for your project?
This is "the public list to talk about the Open Source Geospatial
Foundation (OSGeo) in general" with many subscribers who are not
interested in programming or any other low-level technical trivias.

My build directories are:
~/build/perfecttin/cdbg for the debug build (prefix $HOME),
~/build/perfecttin/crel for the release build (prefix $HOME),
~/build/perfecttin/cins for the release build (prefix /usr/local),
~/build/perfecttin/cafl for fuzzing (prefix $HOME, but installing disabled),
and the same with 'g' instead of 'c', compiled with g++ instead of clang. I
added a desktop file and installed it and the icon under $HOME, then symlinked
~/share/applications/perfecttin.desktop to ~/.local/share/applications/
perfecttin.desktop . It showed up in the menu, but had no icon and didn't run.
I then installed under /usr/local and it worked perfectly.
Apparently I should install under ~/.local/, but the only directory under
~/.local is share; ~/.local/bin, ~/.local/include, and ~/.local/lib do not
exist. Should I add ~/.local/bin to PATH, or should I make symlinks in ~/bin/?

Re: [OSGeo-Discuss] How to set SHARE_DIR?
I wouldn't expect someone to set CMAKE_INSTALL_PREFIX=$HOME. That just seems
like a good way to cause issues to me.
There is a ~/.local/share directory and a ~/.local/share/applications directory
in my home directory that has desktop files in it. (That might imply using
CMAKE_INSTALL_PREFIX=$HOME/.local is possible but that still seems like it is
asking for trouble.)
Standard practice is to put the files under ${CMAKE_INSTALL_PREFIX}/share/
unless the user specifically overrides that. I consider it hostile behavior when an
installer or build system starts putting files outside of the path(s) that I have
specified for it. I can make symlinks for files in ${CMAKE_INSTALL_PREFIX}/share to
~/.local/share/applications manually if I want to.
As an aside, I personally tend to install locally built applications under
~/apps/// where is something like GIS, and
would be like QGIS or PDAL, and version is the release or the output of 'git describe --tags'.
This lets me keep multiple versions of installed applications which is particularly useful for regression
testing and/or ensuring a long job is completed using one version of a program while I can start new jobs
with newer versions. I have a (git) versioned build.sh script for each application that does things like
make directories, call cmake/make/make test/make install, and sometimes updates desktop files and module
files (see the environment-modules Debian package). Occasionally I have special builds with custom patches
for a particular task. These fit the structure too (they have a different git tag/hash).
If build systems started messing around with files in
~/.local/share/applications behind my back, it would make a real mess of not
being certain what build a desktop file was pointing to.

One of the lines in the desktop file tells where the icon is. PerfectTIN has a
256×256 pixel icon. Do I have to shrink it for the desktop file?
