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/<app>
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/<category>/<app>/<version> where <category> is something like GIS, and
<app> 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.

I've been setting SHARE_DIR to ${CMAKE_INSTALL_PREFIX}/share/<app>. If I put
the desktop file in ${CMAKE_INSTALL_PREFIX}/share/applications/, that would be
correct for a system-wide install, but wrong for a personal install. I checked
SHARE_DIR in CMakeLists files seven levels deep (PDAL has some that are that
deep), but found none that set SHARE_DIR to anything else. Is there another
CMake variable that tells where desktop files go?
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?
