I was tempted to go ahead and file a bug on this; but it seems so basic
that I figure I must be missing something.
Per the documentation for find_program:
If NO_DEFAULT_PATH is not specified, the search process is as
follows:
⋮
5. Search the standard system environment variables. This can be
skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
* PATH
That indicates to me that for "find_program(PROG_VAR NAME foo)", CMake
ought to find "foo" if "foo" is in the PATH. That doesn't seem to be
the case, though. A concrete example:
cmake_minimum_required(VERSION 3.0)
cmake_policy(SET CMP0048 NEW)
project("hello" VERSION 0.1.0 LANGUAGES C)
find_program(GETTEXT_MSGMERGE_EXECUTABLE NAME msgmerge)
message(STATUS "GETTEXT_MSGMERGE_EXECUTABLE =
${GETTEXT_MSGMERGE_EXECUTABLE}")
add_executable(hello hello.c)
This outputs:
$ cmake -G "Unix Makefiles" ~/src/hello
-- GETTEXT_MSGMERGE_EXECUTABLE = GETTEXT_MSGMERGE_EXECUTABLE-NOTFOUND
-- Configuring done
-- Generating done
-- Build files have been written to: /home/mcdanb/build/hello
$ which msgmerge
/usr/bin/msgmerge
I am using CMake 3.14.5.
Have I misunderstood the documentation on this point?
