OpenCV VS 2010 C++ CMake -

i couldn't find answer simple question. have been having problems getting opencv work on computer either dev c++ or vs 2010.

my question not specifics instead cmake contributes process.

i have worked way through lot of c++ programs, learning language. however, wrote them , compiled them, no fuss, directly on dev c++ using standard includes, etc..

now wehn come try use first 3rd party set of libraries, there huge process of downloading executable, using cmake, compiling 1 of ides. me, there no wonder thing goes wrong. many steps , purpose?

ok, naive , simple programming. here questions:

why there executable if have 3 steps afterwards? sort of understand if writers have no idea compiler using; why not simple set of source codes , done it?

however, if there specific file vs 2010, why not have set way work on computer?, same way downloads vs 2010 in same format , installs itself?

finally, if sort of installer needed create directory structure (which still don't understand since zip, tar, etc. work fine), why there need cmake @ all?

i don't mind being laughed @ being stupid , missing obvious points, appreciate not having wade through quick retorts: may seem simple y'all outside, doesn't make sense. in advance, john

thanks. guess don't understand enough details of process understand why necessary. or rather, sort of understand: there different operating systems , different compilers, though coding different each, cmake understands compilers has listed , developer need figure out how write cmake. if cmake doesn't understand environment or compiler, library authors or developer has figure out how port particular environment. however, still don't understand why case of vs 2010, since opencv has particular compiler in mind, cmake necessary. however, leave alone moment , move on.

thanks again.

i think need add comment. in response question "is of issue?" think answer has yes. have wasted week trying opencv work vs 2010.

no one, microsoft websites independent blogs has been able me. have gone through sxstrace, etc. , tried has suggested. in end same problem.

so yes issue. not trying learn windows programming @ moment. nor want learn cmake intricacies @ time. .exe programs install windows have worked me. sure there exceptions there aren't. if opencv putting out special 2008.exe version, why not make work way.

by way, here output of sxstrace text file:

i think might misunderstand cmake benefits most. it's library authors, , reason. when authoring cross-platform library, need provide build environments different operating systems , compilers. there quite few combinations. maintaining these make-files , projects/solutions large library projects labour-intensive task, if new file has been added or removed.

cmake takes pain out of this. generates build in compiler-independent-manner, allowing authors of source code maintain single build environment. project can distributed across platforms , compilers easily.

so yes, it's step developer using library, have build once-per-release, of issue?
