Solution
open build.make in below project path
httpd-2.4.33\httpdbin\CMakeFiles\mod_lbmethod_bybusyness.dir\depend.make
search for link.exe and go to next line and add the mod_proxy.lib as shown below.
/out:mod_lbmethod_heartbeat.so /implib:mod_lbmethod_heartbeat.lib /pdb:C:\gitcode\httpd-2.4.34\httpdbin\mod_lbmethod_heartbeat.pdb /dll /version:0.0 /base:@C:/gitcode/httpd-2.4.34/httpdbin/BaseAddr.ref,mod_lbmethod_heartbeat.so /machine:x64 /INCREMENTAL:NO libhttpd.lib ..\srclib\apr\Release\lib\libapr-1.lib ..\srclib\apr-util\Release\lib\libaprutil-1.lib ws2_32.lib mswsock.lib ..\srclib\pcre\Release\lib\pcre.lib ws2_32.lib mswsock.lib kernel32.lib user32.lib gdi32.lib winspool.lib shell32.lib ole32.lib oleaut32.lib uuid.lib comdlg32.lib advapi32.lib mod_proxy.lib
