Not sure I understand neither your spec nor your code to their entirety. Howsoever, would

Code:

awk -F\| -vREG=$1 '
$1 ~ "^" REG    {gsub (/^ | $/, "", $4)
                 print "path =", $4
                 system ("echo cd " $4 " && echo \"in the subshell\" && echo $pwd && echo \"exit subshell\" && exec pwd")
                }
 ' file

come close to what you need?

curl-config

curl-config(1)							curl-config manual						    curl-config(1)

NAME

       curl-config - Get information about a libcurl installation

SYNOPSIS

       curl-config [options]

DESCRIPTION

       curl-config displays information about the curl and libcurl installation.

OPTIONS

       --ca   Displays the built-in path to the CA cert bundle this libcurl uses.

       --cc   Displays the compiler used to build libcurl.

       --cflags
	      Set  of  compiler options (CFLAGS) to use when compiling files that use libcurl. Currently that is only the include path to the curl
	      include files.

       --checkfor [version]
	      Specify the oldest possible libcurl version string you want, and this script will return 0 if the current installation is new enough
	      or it returns 1 and outputs a text saying that the current version is not new enough. (Added in 7.15.4)

       --configure
	      Displays the arguments given to configure when building curl.

       --feature
	      Lists what particular main features the installed libcurl was built with. At the time of writing, this list may include SSL, KRB4 or
	      IPv6. Do not assume any particular order. The keywords will be separated by newlines. There may be none, one, or several keywords in
	      the list.

       --help Displays the available options.

       --libs Shows the complete set of libs and other linker options you will need in order to link your application with libcurl.

       --prefix
	      This  is	the prefix used when libcurl was installed. Libcurl is then installed in $prefix/lib and its header files are installed in
	      $prefix/include and so on. The prefix is set with "configure --prefix".

       --protocols
	      Lists what particular protocols the installed libcurl was built to support. At the time of writing,  this  list  may  include  HTTP,
	      HTTPS, FTP, FTPS, FILE, TELNET, LDAP, DICT. Do not assume any particular order. The protocols will be listed using uppercase and are
	      separated by newlines. There may be none, one, or several protocols in the list. (Added in 7.13.0)

       --static-libs
	      Shows the complete set of libs and other linker options you will need in order to link your  application	with  libcurl  statically.
	      (Added in 7.17.1)

       --version
	      Outputs version information about the installed libcurl.

       --vernum
	      Outputs version information about the installed libcurl, in numerical mode.  This outputs the version number, in hexadecimal, with 8
	      bits for each part; major, minor, patch. So that libcurl 7.7.4 would appear as 070704 and libcurl 12.13.14 would appear as 0c0d0e...
	      Note that the initial zero might be omitted. (This option was broken in the 7.15.0 release.)

EXAMPLES

       What linker options do I need when I link with libcurl?

	 $ curl-config --libs

       What compiler options do I need when I compile using libcurl functions?

	 $ curl-config --cflags

       How do I know if libcurl was built with SSL support?

	 $ curl-config --feature | grep SSL

       What's the installed libcurl version?

	 $ curl-config --version

       How do I build a single file with a one-line command?

	 $ `curl-config --cc --cflags` -o example example.c `curl-config --libs`
