checking for ICU_MODULE... no configure: error: Package requirements (icu >= 0.21) were not met:
No package 'icu' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.
Alternatively, you may set the environment variables ICU_MODULE_CFLAGS and ICU_MODULE_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. root@umbrella:/tmp/123/qtmltfs2.4#
