[LU-16969] Remove the PKG_CHECK_MODULE macro

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.16.0
• Severity: 3
• Assignee: Tim Day
• Reporter: Tim Day

Description

This macro fails in very annoying to debug ways, without providing any benefit over a plan pkg-config command. Often, this will fail with:

syntax error near unexpected token `LIBNL3,'

`      PKG_CHECK_MODULES(LIBNL3, libnl-genl-3.0 >= 3.1)'

and provide no indication that the real error is that pkg-config is not installed. Using the raw command will make this self-evident will still performing the same function.
