My c programm(for linux) needs users to have a specific programm lets say "foo" be installed to work. I am using cmake to generate build files.
This program is to be distributed.
How can I make sure that it is installed using cmake.
I found this but it's for checking at runtime. I want to check it before building the program.
CodePudding user response:
If foo
provides a CMake package, use find_package
to find foo
:
find_package(foo REQUIRED)
# Use the foo::foo imported target or foo_EXECUTABLE cache variable
There are many built-in packages for CMake including Python
and FLEX
.
If foo
does not provide a CMake package and you only need the path to the executable, then you can use find_program
:
find_program(Foo_EXECUTABLE foo REQUIRED)
From here you can use the Foo_EXECUTABLE
variable in your execute_process
or add_custom_command
calls.
