awk to combine lines from line with pattern match to a line that ends in a pattern

I am trying to combine lines with these conditions:
1. First line starts with text of "libname VALUE db2 datasrc" where VALUE can be any text.
2. If condition1 is met then continue to combine lines through a line that ends with a semicolon.
3. Ignore case when matching patterns and remove any leading spaces from line when joining.

I have tried to code this using awk or sed without success.

Input file:

Code:

libname &wrk_schema DB2 database = %sysget( DB2DBDFT ) schema = &wrk_schema read_isolation_level = ur ;
libname schema db2 datasrc=%sysfunc(sysget(DB2DBDFT)) schema=&qmt_schema read_isolation_level=ur;
libname db2lib db2 datasrc=crd_prod ;
libname server db2 datasrc=%sysfunc(sysget(DB2DBDFT)) ril=ur;
libname server db2 datasrc=%sysfunc(sysget(DB2DBDFT));
libname server db2 datasrc=%sysfunc(sysget(DB2DBDFT))
            schema = &build_schema
            access = readonly
            connection = globalread
            read_isolation_level=ur;
libname server2 db2 datasrc=%sysfunc(sysget(DB2DBDFT))
             schema = &build_schema2
             access = readonly
             connection = globalread
             read_isolation_level=ur;

Desired Output file:

Code:

libname &wrk_schema DB2 database = %sysget( DB2DBDFT ) schema = &wrk_schema read_isolation_level = ur ;
libname schema db2 datasrc=%sysfunc(sysget(DB2DBDFT)) schema=&qmt_schema read_isolation_level=ur;
libname db2lib db2 datasrc=crd_prod ;
libname server db2 datasrc=%sysfunc(sysget(DB2DBDFT)) ril=ur;
libname server db2 datasrc=%sysfunc(sysget(DB2DBDFT));
libname server db2 datasrc=%sysfunc(sysget(DB2DBDFT)) schema = &build_schema access = readonly connection = globalread read_isolation_level=ur; 
libname server2 db2 datasrc=%sysfunc(sysget(DB2DBDFT)) schema = &build_schema2 access = readonly connection = globalread read_isolation_level=ur;

grep

GREP(1) 						      General Commands Manual							   GREP(1)

NAME

       grep - search a file for lines containing a given pattern

SYNOPSIS

       grep [-elnsv] pattern [file] ...

OPTIONS

       -e     -e pattern is the same as pattern

       -c     Print a count of lines matched

       -i     Ignore case

       -l     Print file names, no lines

       -n     Print line numbers

       -s     Status only, no printed output

       -v     Select lines that do not match

EXAMPLES

       grep mouse file	   # Find lines in file containing mouse

       grep [0-9] file	   # Print lines containing a digit

DESCRIPTION

       Grep  searches  one  or	more  files (by default, stdin) and selects out all the lines that match the pattern.  All the regular expressions
       accepted by ed and mined are allowed.  In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or  1
       occurrences,  and  |  can  be used between two regular expressions to mean either one of them.  Parentheses can be used for grouping.  If a
       match is found, exit status 0 is returned.  If no match is found, exit status 1 is returned.  If an error is detected,  exit  status  2	is
       returned.
