No rule to make .exe file when TARGET=LINUX is set

Hi @juliena82 ! = ) I am almost at the finish line! = ) Now, after all compiles nicely, there is a strange link error:

$ export TARGET=LINUX
$ make

How should the Makefile be modified in order to exclude the .exe file on Linux?

[valera-rozuvan]

I have compiled it! It is alive = ) OK. So I got it to compile on latest stable Debian. With some minor hiccups... Fix is already in master = )

Issue resolved in commit 21c5ddfd4037f49daac9ae10b3c3343822c74a01.

Great job @valera-rozuvan, sounds like you're almost done :)

[juliena82]

Congratulations! For the link error, it is strange that it appears with some linux distribution and not with another... At this point, the error is caused by the Makefile not finding a required dependance for building the executable. It may be for instance that ocvext or libcutil were not build, or another external Library is missing.
