Máté,

I don’t know anything about the CMAKE_EXPORT_COMPILE_COMMANDS feature, but I 
can attest that the UseLATEX commands are all created with add_custom_command 
(with some add_custom_target commands to set up the targets). Someone who knows 
the CMAKE_EXPORT_COMPILE_COMMANDS feature will have to answer whether it is 
possible to export custom commands.

Subject: [EXTERNAL] [CMake] custom_command and compile_commands.json

Hi!

I am trying to export a custom_command to the compile_commands.json database, 
but no luck up until now. The only similar question I found on the web is a 
Stackoverflow thread named „cmake clang-tidy (or other script) as custom 
target”.

I am trying to bring together C/C++ compilation, GnuPlot and LaTeX into a 
single Cmake script (done), and have the relevant Visual Studio Code extensions 
hook into the compile_commands.json file to recognize CMakes machinery and that 
they themselves are not responsible for kicking off the compilation of their 
respective source files. Microsofts C++ extension is compile_commands.json 
aware, but the LaTeX-Workshop extensino is not. I wanted to do the research 
before jumping to feature requests: is it possible to export @kmorel Github 
users UseLATEX custom_commands into the compile_commands.json database? As far 
as I saw, setting CMAKE_EXPORT_COMPILE_COMMANDS to ON right before 
add_latex_document() is not enough. Does LATEX need to be a first-class CMake 
language in order for this machinery to kick off?


Tanks in advance,
Máté
