When building libicu on ubuntu, where do I define U_USING_ICU_NAMESPACE?

I am building libicu on Ubuntu Linux.

In Recommended Build Options, the documentation suggests that I should use -DU_USING_ICU_NAMESPACE=0 and -DU_CHARSET_IS_UTF8=1.

My build process is as follows.

wget -nv http://download.icu-project.org/files/icu4c/55.1/icu4c-55_1-src.tgz -O icu4c-55_1-src.tgz
tar -zxvf icu4c-55_1-src.tgz 
mkdir -p build
cd build
../icu/source/runConfigureICU Linux
make check

Where do I provide the arguments -DU_USING_ICU_NAMESPACE=0 and -DU_CHARSET_IS_UTF8=1? Neither configure nor make seem to accept these arguments.

For command line try using: CPPFLAGS="-DU_CHARSET_IS_UTF8=1" see here

So your command-line becomes 

wget -nv http://download.icu-project.org/files/icu4c/55.1/icu4c-55_1-src.tgz -O icu4c-55_1-src.tgz
tar -zxvf icu4c-55_1-src.tgz 
mkdir -p build
cd build
CPPFLAGS="-DU_CHARSET_IS_UTF8=1" ../icu/source/runConfigureICU Linux
make check

Or you can modify the headers directly. see here Good if you're rebuilding a lot and want a simple command line but does require you to re-apply the change should the source file get updated.
