I'm trying to compile OCR 0.4, an optical recognizing program by Google.
As written in the readme file they require to:
1) make sure you have these packages installed (current Ubuntu/Debian versions should work): libpng (with headers) libjpeg (with headers) libtiff (with headers)
2) install iulib from http://code.google.com/p/iulib
3) install a current version of tesseract from the Subversion repository (http://code.google.com/p/tesseract-ocr)
4) from the release directory, run ./configure make sudo make install
I've done all their passages above then when I type "./configure" into the command line I get this error:
checking for /usr/include/tesseract/baseapi.h... no configure: error: Could not find tesseract! Choose --without-tesseract if you do not want to use it or specify the installation path with --with-tesseract=
What I tried to solve this so far, is try to compile by specifying the tesseract path I got by typing "which tesseract"that gives me
/usr/local/bin/tesseract
So I typed ./configure --with-tesseract=/usr/local/bin/tesseract and I got the same identical error.
Why am I getting this?
Thanks in advance
EDIT - After I've used the method stated in the answer below I get the following error:

Per the documentation on OCRopus, could you try:
./configure --with-tesseract=/usr/local
