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;

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
