Actually, I wanted to clarify that this is (partial output) what I get at the "cmake..." step:

-------------------------------
[...]
-- Using system zlib
-- Could NOT find MXML (missing: MXML_LIBRARIES MXML_INCLUDE_DIRS)
-- Building bundled mxml due to missing system mxml
-- Found system libbz2
-- Could NOT find LZMA (missing: LZMA_LIBRARIES LZMA_INCLUDE_DIRS)
-- Could NOT find DCMTK (missing: DCMTK_config_INCLUDE_DIR DCMTK_ofstd_INCLUDE_DIR DCMTK_ofstd_LIBRARY DCMTK_dcmdata_INCLUDE_DIR DCMTK_dcmdata_LIBRARY DCMTK_dcmimgle_INCLUDE_DIR DCMTK_dcmimgle_LIBRARY)
-- DCMTK library not found - defaulting to bundled version.
-- Building bundled DCMTK library for DICOM support.
-- BUILD_TESTING is active - building numdiff for tolerant numerical comparisons
[...]
-- Configuring done
-- Generating done
-- Build files have been written to: cmtk/3.3.2
-----------------------------

and then at the "make..." step I get warnings regarding several include *.h files are not found and this at the end:
