[MPlayer-cygwin] mingw\bin\ld.exe: cannot find -ljpeg [solved]

[compn]

i was having some trouble getting -ljpeg and -lpng and -liconv working
i kept getting messages like
d:\mingw\bin\..\lib\gcc-lib\mingw32\3.2.3\..\..\..\..\mingw32\bin\ld.exe: cannot find -ljpeg

running ld -verbose -l jpeg would output something like

attempt to open d:\mingw\bin\../mingw32/lib/libjpeg.dll.a failed

but /usr/lib/libjpeg.a was there.
i found out that ld.exe will only 'find' libjpeg.a if its in /mingw/lib/

same with jpeglib.h in /mingw/include and not /include

this is probably just my mingw build and not putting /include in the right area

just thought i'd post this for future reference.
