Subject: Set the path of pkg-config in a variable instead of hardcoding it
X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=e23acb9188b7bc7a7cfc418ac45671003abcc341;p=st.git

Set the path of pkg-config in a variable instead of hardcoding it

In this way the path of pkg-config can be overridden from the command
line. This is useful for example when cross-compiling.
